How to play
- The row at the top shows the locks you must open, in order. The next one is outlined.
- Keys hang on hooks like stacks: only the top key of a hook can be taken, and a hook holds at most four.
- Tap a hook, then press Open the lock if its top key matches the next lock. Or tap another hook to move that key there.
- Open every lock before you run out of moves. Opening a lock counts as a move too.
Controls: mouse or touch. Made by CalcoTools.
Tips and strategy
- Look at the next two or three locks, not just the next one.
- Keep one hook as free space for shuffling keys out of the way.
- Moving a key that is in the way costs a move, so find the key you need to uncover first.
- The move limit is just above a known solution, so there is a little room but not much.
FAQ
- Is every level solvable?
- Yes. Levels are built backwards from the finished position, so a solution always exists, and the move limit is just above it.
- Can I undo?
- Yes. Undo takes back your last action, and Restart starts the level again.
- Does opening a lock count as a move?
- Yes. Every open and every key move counts, so the total is the length of your whole plan.
